A plug-in device enclosing Ai (Artificial intelligent) and IoT (Internet of Things) and a method for linking AC wiring devices and AC loads via cascading optical grid for exchanging at least one of two way communication through the optical cascading grid, enabling to introduce and assign AC switches and AC outlets and link optically the entire electric device of a residential and commercial units and communicate the power consumed and the loads statuses, at all time, and limiting the WiFi communication to a single transmitter at the time, to ensure no error communication.

An isolator includes a conditioning circuit configured to condition signals communicated therethrough. The isolator also includes a coupling member that includes an anti-rotation feature. The anti-rotation feature is configured to prevent the conditioning circuit from rotating with respect to the coupling member. The isolator also includes a coaxial circuit positioned around the coupling member. The coaxial circuit is configured to at partially attenuate direct current (DC) signals.

An isolator includes an input connector configured to connect the isolator to a first device. The isolator also includes an output connector configured to connect the isolator to a second device. The isolator also includes a body including an outer shield. The isolator also includes a coupling member positioned at least partially within the outer shield. The coupling member is configured to electrically couple with the outer shield. The isolator also includes a coaxial circuit positioned at least partially around a first portion of the coupling member. The isolator also includes a toroid positioned at least partially around a second portion of the coupling member The isolator also includes a compression material configured to apply a force to the coaxial circuit and the toroid. The isolator also includes a signal conditioning circuit configured to condition signals communicated between the input connector and the output connector.

A torque-limiting torque sleeve may include an inner sleeve and an outer sleeve configured to be coupled to one another in a coaxial arrangement such that the outer sleeve is fixed relative to the inner sleeve in the longitudinal direction. A first end of the outer sleeve overlies a first end of the inner sleeve, and a second end of the inner sleeve extends from the outer sleeve. A torque limiting feature is configured such that rotation of the outer member in a first direction enables tightening of a coupler on an interface port up to a predetermined torque limit, and rotation of the outer member in a second direction opposite to the first direction loosens the coupler on the interface port.
